  Nucleophilic additions of Grignard reagents to N-benzyl-2,3-O-isopropylidene-D-glyceraldehyde nitrone (BIGN). Synthesis of (2S,3R) and (2S,3S)-3-phenylisoserine

  摘要：

  A remarkable Lewis acid tuning has been observed in the nucleophilic addition of Grignard reagent to BIGN, the N-benzyl nitrone derived from 1,2-O-isopropylidene-D-glyceraldehyde. The obtained alpha,beta-dialkoxy hydroxylamines can serve as starting points for the synthesis of both aminodiols and alpha-hydroxy-beta-amino acids. This synthetic approach is illustrated by the synthesis of the antipode of the C-13 side chain of Taxotere as well as its C-3 epimer. (C) 1998 Elsevier Science Ltd. All rights reserved.

• Asymmetric Synthesis of ES-285, an Anticancer Agent Isolated from Marine Sources

  The asymmetric synthesis of (2S,3R)-2-amino-3-octanedecanol hydrochloride (ES-285·HCl) was achieved in eight steps in ca. 38 % overall yield from the N-benzylimine-derived from (R)-2,3-O-isopropylidene glyceraldehyde, which is easily available on gram scale from the inexpensive precursor D-mannitol. Highly diastereoselective addition of methylmagnesium bromide to the N-benzylimine was the key step

  (2S,3R)-2-amino-3-octanedecanol 盐酸盐 (ES-285·HCl) 的不对称合成在大约 8 个步骤中完成。来自 (R)-2,3-O-异亚丙基甘油醛的 N-苄亚胺的总产率为 38%，它很容易从廉价的前体 D-甘露醇以克规模获得。将甲基溴化镁高度非对映选择性地添加到 N-苄亚胺中是创建具有适当构型的 vic-氨基醇部分的关键步骤。中间体氨基环氧化物的区域选择性开环能够在 C4 处引入长烃链。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

  日期：1997.6

  The stereoselective addition of Grignard reagents to alpha-alkoxy nitrones has been achieved with excellent stereocontrol using ZnBr2 and Et2AlCl as precomplexing agents to obtain the corresponding syn- and anti- adducts, respectively. The obtained hydroxylamines have been transformed into valuable 3-amino-1,2-diols. (C) 1997 Elsevier Science Ltd.
• Diastereoselective reduction of ketimines derived from (R)-3,4-dihydroxybutan-2-one: an alternative route to key intermediates for the synthesis of anticancer agent ES-285

  A simple and convenient procedure for the diastereoselective reduction of imines derived from (R)-3,4-dihydroxybutan-2-one is described. The use of sodium borohydride as a reducing agent in the reactions with pre-synthesised imines gave aminodiol derivatives with the appropriate stereochemistry for use as intermediates in the synthesis of anticancer agent ES-285. The aminodiols were isolated in ca. 62% yield. (C) 2010 Elsevier Ltd. All rights reserved.
